I've loaded the 2.7.0 beta for Mac arm and all's good so far. I had to reread the thread to see where the Automate feature had vanished to, but I've got it working.
I made a new automation to run 2 saved searches:
1. for un-prettifying tables
2. h4 to h3, from the saved search examples.
My un-prettifying saved search ran ok but the automation couldn't recognise the name of the heading change search, even when it was copy/pasted from saved searches.
Code:
RunSavedSearchReplaceAll h4 to h3 running
Missing or unknown Saved Search name: RunSavedSearchReplaceAll h4 to h3
RunSavedSearchReplaceAll h4 to h3 failed
Automation List Failed
'h4 to h3' worked fine outside the automation when directly loaded from saved searches.
